DETAILED DESCRIPTION

(8) The following detailed description of embodiments of the invention references the accompanying drawings. The embodiments are intended to describe aspects of the invention in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments can be utilized and changes can be made without departing from the scope of the claims. The following detailed description is, therefore, not to be taken in a limiting sense. The scope of the present invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled.

(9) In this description, references to one embodiment, an embodiment, or embodiments mean that the feature or features being referred to are included in at least one embodiment of the technology. Separate references to one embodiment, an embodiment, or embodiments in this description do not necessarily refer to the same embodiment and are also not mutually exclusive unless so stated and/or except as will be readily apparent to those skilled in the art from the description. For example, a feature, structure, act, etc. described in one embodiment may also be included in other embodiments, but is not necessarily included. Thus, the present technology can include a variety of combinations and/or integrations of the embodiments described herein.

(10) Turning now to the drawing figures, and initially FIG. 1, a container assembly 10 constructed in accordance with an embodiment of the invention is illustrated. The container assembly 10 broadly includes a container 12 for enclosing a food item, medication, or other product that should not be used after an expiration date; a sensor 14 for sensing when the container 12 has been opened; an alarm 16; and a timing circuit 18 coupled with the sensor 14 and the alarm 16 for triggering the alarm. The container assembly also includes power terminals or connectors for connecting to a battery or other power source for powering the alarm 16 and timing circuit 18. Importantly, the timing circuit 18 only triggers the alarm 16 if the container 12 is opened after the expiration date has been reached so as to preserve the life of the battery that powers the timing circuit 18.

(11) The container 12 may be any size and shape and configured to enclose any type or quantity of product. For example, as shown in FIG. 3, one embodiment of the container 12 may be in the form of a jar 20 with a twist-off lid 22. Such a container may store industrial chemicals, compounds, food items, medication ointments, beauty creams, etc. Another embodiment of the container 12 is shown in FIG. 4 and is in the form of a medicine vial 24 with a snap-off lid 26. Such a container may store pills, capsules, or other medicines. In other embodiments, the container 12 may be a sealable bag, tube, sack, box, bottle, can, etc. As shown in FIG. 5, the container may include a lashing, strap, or other device 28 that must be unbuckled, cut, or otherwise removed to access a product in a barrel, box, or other container 30. The container may be designed for one time use or designed to be refilled and reused multiple times.

(12) The sensor 14 may be any device that senses or detects when the container 12 is opened. For example, the sensor 14 may be a switch or light sensor that determines when the lid 22 shown in FIG. 3 or the lid 26 shown in FIG. 4 has been removed from its container. The sensor may also detect when a lashing, strap, or other securement device is unbuckled, cut or otherwise removed to provide access to a product. The sensor 14 may alternatively include electrical contacts that form an electrical path between the container and the timing circuit 18, wherein the electrical path is broken to trip a switch when the lid 22 or lid 26 is removed from its container. The sensor 14 may be configured to only detect when the container 12 is first opened or may detect each time the container is opened. This latter embodiment is useful for containers that store products that are used over time.

(13) The alarm 16 may be any device that can alert a user when triggered by the timing circuit 18. For example, the alarm 16 may be an audible alarm such as a beeper, bell, or speaker; a visual alarm such as an LED light; or a combination audible/visual alarm. In some embodiments of the invention, the alarm 16 may include a wireless transmitter configured to transmit an alert from the timing circuit 18 to a remote device such as a computer, tablet, smart phone, or the like.

(14) The timing circuit 18 may comprise any number or combination of processors, circuits, integrated circuits, programmable logic devices, programmable logic controllers (PLCs), or motion programmable logic controllers (MPLCs), computers, processors, microcontrollers, transmitters, receivers, other electrical and computing devices, and/or residential or external memory for storing data and other information. The timing circuit 18 may store one or more expiration dates and is operable to count-down the expiration dates or otherwise determine when they have expired. The timing circuit 18 also monitors the state of the sensor 14 and triggers the alarm 16 only if the container 12 is opened after an expiration date for a product stored in the container 12 has expired. When the sensor 14 and timing circuit 18 sense that the container 12 has been opened before the expiration date, the timing circuit 18 does not trigger the alarm 16.

(15) The timing circuit 18 may be configured to implement any combination of algorithms, subroutines, computer programs, or code segments corresponding to method steps and functions described herein. The timing circuit and computer programs described herein are merely examples of circuitry and programs that may be used to implement the present invention and may be replaced with or supplemented with other devices and/or programs without departing from the scope of the present invention. While certain features of the invention are described as residing or performed by in the timing circuit 18, the invention is not so limited, and those features may be implemented elsewhere.

(16) Computer programs or code segments implemented by the timing circuit 18 may comprise ordered listings of executable instructions for implementing logical functions in the timing circuit. The computer programs can be embodied in any computer-readable medium for use by or in connection with any instruction execution system, apparatus, or device. In the context of this application, a computer-readable medium can be any physical medium that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. The computer-readable medium can be, for example, but not limited to, an electronic, magnetic, optical, electro-magnetic, infrared, or semi-conductor system, apparatus, or device. More specific, although not inclusive, examples of the computer-readable medium include the following: an electrical connection having one or more wires, a portable computer diskette, a random access memory (RAM), a read-only memory (ROM), an erasable, programmable, read-only memory (EPROM or Flash memory), a portable compact disk read-only memory (CDROM), an optical fiber, multi-media card (MMC), reduced-size multi-media card (RS MMC), secure digital (SD) cards such as microSD or miniSD, and a subscriber identity module (SIM) card.

(17) FIG. 2 illustrates a container assembly 10A constructed in accordance with another embodiment of the invention. As with the container assembly 10 described above, the container assembly 10A broadly includes a container 12A for enclosing industrial chemicals, industrial compounds, food items, medications, or other substances that should not be used after an expiration date; a sensor 14A for sensing when the container 12 has been opened; an alarm 16A; and a timing circuit 18A coupled with the sensor 14A and the alarm 16A for triggering the alarm. The container 12A, sensor 14A, alarm 16A, and timing circuit 18A are substantially identical to the like-numbered components described above. In this second embodiment, the container assembly 10A also includes a user interface 28A for permitting a user to enter the expiration date or a time period into the timing circuit 18A. The user interface may be a touchscreen display, one or more buttons, or any other mechanism for entering data into the timing circuit. The container assembly 10A may further include a display 30A coupled with the timing circuit 18A for displaying the expiration date and a time period remaining before the expiration date is reached. In come embodiments, the user interface 28A and display 30A are a single device.
